FUBRING AND FASTENING DEVICE.

Application filed May 16, 1922. Serial No. 561,275.

To all whom it may concern:

Be it known that 1 ORiN T. Cnown, residing at Hayward, in the county of Alameda and State of California, have invented a new and useful. Furring and Fastening Device, of which the following is a specification.

This invention relates to devices for the fnrring of walls, and in particular to such a device in the form of a staple adapted to use with wire lat-hing, the combination forming the anchoring or foundation means to receive and support a plaster or cement coating for walls or the like.

The present invention is an improvement on my previous invention of like character, and which has been patented to me May 15, 1923, Patent No. 1,455,243.

The present common method of anchoring plaster to the exterior walls, of bungalows and buildings, is by laying wire mesh lathing over vertically positioned wooden furring strips, spaced about eight inches apart and nailed over building paper to the sheathing'of the building. Plaster is then spread over the wall surface flush with the wooden furring strips; the latter bedded therein, soon absorb moisture andswell. As the plaster dries, the. strips shrink more or less, thus unequal stresses are set up in the wall, resulting, upon close examination in fine hair-like cracks throughout the wall. These cracks tend to become longer and wider as the annual seasonal changes take place, and eventually patches of plaster drop off.

The main object of my invention is to overcome the above initial fine cracks, and thus extend the life of the wall to a very marked degree and present an uniform and continuous surface. Other important objects of the furring device are, the quick application of it to the sheathing and building paper, and its effective holding power, its uniform outstanding distance from the sheathing surface, and the ease of application of the wire lathing over and to the bearing surface of the staples, and their cheapness of production and simplicity.

An object of importance in my present invention differing from said issued patent, is that fewer staples per given area are required but the same are of greater length suiiicient to support a greater width of wire lathing, In some cases I may prefer to use staples of length equal to the Width of the wire fabric. WVhen such staples are positioned, a roll of fabric may be unrolled thereon and secured thereto, in a manner similar to the application of the building paper to the wood sheathing.

My improved staples, while but two pronged, have spaced indents thereon of fixed depth for wall-contact support. This insures the wire lathing supported thereon, to outstand an uniform and fixed distance from the paper-sheathed wall. The indents are also for another purpose, namely, to form notches for the reception and the bedding therein, of the head of the ordinary staple driven into the sheathing for holding the wire lathing on the bearing surface of my improved staple. When such holding staples are positioned, the entire surface of the laid wire fabric is in a plane, and the plaster meshed in and spread, is done so with ease as no staple-head projections are encountered, as is the case in my said patented furring staple.

I attain the above objects by the general formation of the staple and the manner of applying it to the wall as illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of the pre ferred form of my improved staple. Fig. 2-

shows sucha staple in its normal position on a wall, supporting the building paper and the wire lathing; the wall, paper and lathing being shown in section. Fig. 3 is an elevation of a section of wall showing three stages of completion.

Throughout the figures, 1 represents the prong of the staple, 2 its driving head, 3 the shouldered stop-surface and 4: the outstanding supporting or bearing surface of the device. The staple is preferably made of steel wire, formed with a wide mouth, the prongs being pointed and sloping inwardly a little for efiicient driving. The driving head may be formed with a sharp curvature for hammer-surface and its under-portion for available straight-line stop-contact. The outstanding portion 4 may join the hammer head with a blunt curvature to eliminate corners and thus prevent the wire lathing from catching. The out-standing portion of the staple may be in depth equal to the length of the prongs as shown in Fig. 2. In this figure and also in Fig. 3, 5 represents the building surface sheathing, 6 the building paper, 7 the wire lathing and 8 an ordinary staple holding the latter on the supporting surface 4t.

Along the hearing or supporting surface 4; of my staple, are a series of indents or notches 10, spaced apart to any desired Width, and having a depth such that their outside bottom is in a line with the shouldered stop-surtace 3 as shown clearly in Fig. 2. These indents as heretofore mentioned, are for thetwodiold purpose of outstanding; the staple an uniform distance from a wall surface, and for the reception and embed Inent therein of the head of an ordinary holding staple that may be applied thereto.

In Fig. 3 the building paper 6 is shown positioned on the wall and held thereon by the shoulder 3 of the staple; also a section of wire lathing is shown supported on the bearing surface of the staple, and 9 represents the plaster or cement, the finished wall bonded and held firm and stable by the wire lathinp; and staple reinforcing elements.

In operation, the building paper is unrolled on the sheathing; a little, and my staple positioned thereon and driven into the wood until the shoulder 3 contacts the paper, thus the first step is accomplished. The staples are preferably positioned vertically on the sheathing and spaced in stag gered relation. 7

Next the wire lathing' is unrolled upon the of the staples, positioned and stretched and secured thereon by looping an ordinary stapleover the juncture of the lathing with any chosen indent on my furring staple, and driving; the same to holding position, thus completing; the reinforcement foundation for the reception of the first coat of plaster. The plaster may then be spread on, the outstanding lathing insuring an uniform even thickness of plaster, and well anchored to the wall surface, thus allowing the stresses throughout the plaster mass to freely equalize, resulting in a compact homogencous and continuous exterior wall tree from cracks of any nature.

lVhat I. claim in my improved staple as new and desire to secure by Letters Patent of the United States, is the tollowing:--

1.In combination, a wall sheathing, a inultihumped staple of wide span and prong'ed at its extremities, and adapted in be driven in said sheathing to the base ol said humps, and wire lalhingr :ulapted to be I? adapted to be driven in said sheathing to the base of said humps and hold therelwtwnen the said building paper. and wire lathinn adapted to be received and supported on the top of said humps. forming; in conjunctiini therewith outstanding rein'lorcemcnt for stucco wall composition, the latter adapted to he spread on the sheathing surface and between and around the meshes of sa d reinforcement the said humps formed by indeuts on said span, and said indents adapted to receive holding staples over said supported lathing for presenting a flush surface for the unobstructed use of the plasterefis darby.
